Answer: Molar mass of thyroxine is 776.5 g/mol.
Explanation:
Mass of thyroxine = 0.455 g
Mass of benzene = 10g =0.01kg (1 kg = 1000 g)
Formula used :
where,
= change in freezing point =
= freezing point constant =
m = molality
Now put all the given values in this formula, we get
Thus molar mass of thyroxine is 776.5 g/mol.

Answer: 7.41 L of O2
Explanation:
2H2O2(l) ----> 2H2O(l) + O2(g)
22.5 g H2O2 x __1 mol__ x __1 mol O2__ x __22.4 L__ = 7.41 L of O2
34.016 g 2 mol H2O2 1 mol O2
